title: Analgesic narcotic antagonists. 9. 6-Methylene-8 beta-alkyl-N-(cycloalkylmethyl)-3-hydroxy- or -methoxymorphinans.
abstract: Series of N-(cyclopropylmethyl) (P series) or N-(cyclobutylmethyl) (B series) 3-methoxy (1) or 3-hydroxy (2) morphinan-6-ones with hydrogen (a), methyl (b), or ethyl (c) groups in the 8 beta position were converted to the 6-methylene compounds 3 or 4 by reaction with Ph3P = CH2. One member of this new series, N-(cyclobutylmethyl)-8 beta-methyl-6-methylenemorphinan-3-ol (4Bb), had potent mixed agonist-narcotic antagonist properties and, in contrast to the previously studied 6-oxo compound 2Bb, did not substitute for morphine in dependent rats or monkeys.
